Dethiobiotin synthetase; Catalyzes a mechanistically unusual reaction, the ATP- dependent insertion of CO2 between the N7 and N8 nitrogen atoms of 7,8- diaminopelargonic acid (DAPA) to form an ureido ring.

Adenosylmethionine--8-amino-7-oxononanoate aminotransferase; Catalyzes the transfer of the alpha-amino group from S- adenosyl-L-methionine (SAM) to 7-keto-8-aminopelargonic acid (KAPA) to form 7,8-diaminopelargonic acid (DAPA). It is the only animotransferase known to utilize SAM as an amino donor; Belongs to the class-III pyridoxal-phosphate-dependent aminotransferase family. BioA subfamily.

Biotin synthesis protein BioC; Converts the free carboxyl group of a malonyl-thioester to its methyl ester by transfer of a methyl group from S-adenosyl-L- methionine (SAM). It allows to synthesize pimeloyl-ACP via the fatty acid synthetic pathway.

Biotin synthetase; Catalyzes the conversion of dethiobiotin (DTB) to biotin by the insertion of a sulfur atom into dethiobiotin via a radical-based mechanism; Belongs to the radical SAM superfamily. Biotin synthase family.

Coronafacic acid polyketide synthase I; This gene is the first of two multimodular polyketide synthetases involved in the biosynthesis of coronafacic acid. This synthetase is proposed to receive CPC (2-carboxy-2-cyclopentenone) from an acyl carrier protein (cfa1), it then adds a buyrate group and then completely reduces the ketone of the (former) carboxylate group. The resulting product is then passed to the second polyketide synthetase (cfa7); similar to GP:13346874; identified by sequence similarity; putative; see PMID:20190049 for expression data; This gene is the first of two multi [...]

Coronamic acid synthetase CmaA; Non-ribosomal peptide synthetase with adenylation and thiolation domains; reacts with the AMP derivative of L-allo-isoleucine to produce an aminoacyl thiolester intermediate during coronamic acid biosynthesis; see PMID: 14679222; see PMID:20190049 for expression data; non-ribosomal peptide synthetase with adenylation and thiolation domains, reacts with the AMP derivative of L-allo-isoleucine to produce an aminoacyl thiolester intermediate during coronamic acid biosynthesis, see PMID: 14679222.

This gene is aparrently the terminal component of a non-ribosomal peptide synthetase (due to the presence of the terminal thioesterase domain) and is most likely associated with the previous gene which appears to be a initiating component. This gene contains three complete amino acid activation, thiolation and condensation domain modules and appears to be specific for glycine, an unidentified amino acid and serine according to the prediction algorithm at http://raynam.chm.jhu.edu/; nrps/index2.html. Taken together these two genes appear to direct the biosynthesis of a previously undesc [...]

Coronafacic acid polyketide synthetase II; This gene is the second of two multimodular polyketide synthetases involved in the biosynthesis of coronafacic acid. This synthetase is proposed to receive CPE (2-[1-oxo-2-cyclopenten-2-ylmethyl]butanoic acid) from the first synthetase, Cpe6. It then adds one final acetate group, catalyzes the cyclization of the second ring and converts a ketone to a double bond. The product is released by a terminal thioesterase domain; similar to GP:13162634; identified by sequence similarity; putative; see PMID:20190049 for expression data; This gene is the [...]

This gene is aparrently the initiating component of a non-ribosomal peptide synthetase (due to the presence of an initial non-amino acid adenylation/ligase domain) and is most likely associated with the following gene which appears to be a terminating component. This gene contains a thiolation domain as well as one complete amino acid activation, thiolation and condensation domain modules which appears to be specific for serine according to the prediction algorithm at http://raynam.chm.jhu.edu/; nrps/index2.html. Taken together these two genes appear to direct the biosynthesis of a pre [...]
